EUNHTED STATES NICHOLAS A. PETRY, OF PHILADELPHIA, PENNSYLVANIA.

VENTILATOB.

To all whom it may concern Be it known that I, NICHOLAS A. PETRY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented a Ventilator, of which the following is a specification.

One object of this invention is to provide a novel form of ventilator particularly adapted for use on the cowl of a motor vehicle and of such construction as to direct a current of air into the space under and to the rear of said cowl;the invention more particularly contemplating a ventilator adjustable both to vary the volume as well as the direction of flow of the air admitted,

I further desire to provide a. ventilator of the above type which while being substantial and conveniently adjustable as indicated, shall be waterproof when closed, inexpensive to make and easily applied to the cowl of a motor vehicle, or to any other structure on which it is desired to mount it ;the arrangement and structure of parts being such as to make possible the mounting of a ventilator of standard form and dimensions oncowls or other structures of widely differing construction.

These objects and other advantageous ends I attain as hereinafter set forth, reference being had to the accompanying drawings, in which,

Fig. 1 is a perspective view showing my ventilator as applied to the cowl of a motor vehicle;

Fig. 2 is a perspective view on a larger scale than Fig. 1, illustrating the detail construction of the ventilator;

Figs. 3, 4 and 5 are pers ective views-of the parts of the ventilator s own in Fig. 2;

Fig. 6 is an end elevation partly in section;

Fig. 7 is a transverse vertical section of the ventilator shown in Fig. 1; and

Fig. 8 is a perspective view of the frame constituting part of my invention.

In the above drawings 1 represents the cowl of a motor vehicle body and at any desired point such as the middle of this cowl, I form a transversely elongated, substantially rectangular opening in which I mount a ventilator, illustrated in detail in Fig. 2. Said ventilator primarily consists of an open elongated rectangular upper frame 2 whose opening is substantially the same form and dimensions as that of the opening in the Specification of Letters Yatent.

cowl. This is designed to coact with a similar open rectangular frame 4, Fig. 8, having substantially the same form and dimensions. These two frames are preferably made of relatively stiff pressed metal such as steel and the upper frame is formed with an up wardly extending marginal flange 5. The lower frame is preferably of channel section and the two are rigidly connected by bolts so as to clamp the metal of the cowl between them by means of bolts 6 passed through holes 6 in the upper frame 2.

It will be noted that these two frames by reason of their form and material, are sufliciently stiff to bend into their plane the sheet metal of the cowl which is clamped between them, so that they closely fit the surface of said metal at all points regardless of the fact that as originally formed, the portion of the cowl in which the ventilator is mounted usually has a double curved surface. WVhile the lower frame 4 is of substantially the same section at all points, one side of the upper frame 2 is peculiar in that a portion of the metal cut out of its main opening is bent down and back into a plane substantially parallel with that'of the frame forming a .rearwardly projecting flat portion 7 (Figs.

4 and 7) spaced away from the body of the frame a sufiicient distance to permit the 'entrance of the flange of a cover 9.

The rear edge of this side of the frame, instead of being provided with the marginal flange 5, is rolled into tubular form as indicated at 8, being turned upwardly and inwardly. This rolled or tubular edge 8 serves as a bearing or pivotal support for the correspondingly curved edge of the adjustable cover or top 9 of the ventilator which consists primarily of an elongated rectangular plate having its edges flanged as indicated at 10 in Fig. 3 and of such dimensions that it will fit over and completely enclose the upper frame 2 when the ventilator is closed, so as to render the device waterproof.

- Formed integral with this cover'9 are two segmental side plates 11 connected to it by strips 12 and each having pressed out teeth 13 forming notches extending from its outer circularly curvededge in positions to coact with a tooth 15 formed by a turned over or rolled up tongue formed integral with the of its inner side edges. As the metal of the tions or teeth 13.

' form turned up at right angles to its body In the circular edge of each of the segmental end or side members 11 there is formed a substantially radial cut and the metal on one side of this cut is bentoutwardly from the plane of the member to form a, stop 16 im mediately adjacent the lowest one of the recesses 13 so that movement of the cover is limited to a definite angle relatively to the plane of the frame 2. As the cover is raised or lowered, its rear flange and its portion immediately adjacent thereto, turns upon the rolled up edge 8 of the frame, as a bearing and the portion of each of the sides 11 adjacent the rearwardly turned part 7 of the frame is cut away to form a circularly curved edge 17 which engages and slides over the curved inner edge 18 of the frame 2 so as to prevent rearward movement of the cover away from this bearing structure 8.

In order to positively direct the body of air after it is deflected by the raised cover 9 into and through the opening of the frame 2, I provide a deflector or'baflle19 preferably having the detail construction shown in Fig. 5. This consists of a flat elongated body of sheet metal. having ends, 20 of segmental and at such a distance apart as to just fit be tween .the segmental ends 11 of the cover 9. The rear or inner edge portion 21 of this deflector plate is bent slightly out of the plane of the body thereof and has projecting tongues 22 at its ends whlch fit into the space between the edges 17 of the ends 11 and the body of the cover 9. These ends serve as pivots or pintles for the deflector'which is adjustably connected to the ends 11 by bolts 24 operative in elongated slots 25 formed in the turned up ends 20 of said deflector.

In the preferred form of my invention the ends 20 of the member 19 are recessed or pressed toward each other around the slots 25 and the ends 11 of the cover 9 are similarly recessedaround the holes 24 for the bolts 24 in order that the heads of the latter may be flush with or below the outer surfaces of said ends 11 and thereby permit these to be placed in and removed from the openings in the frames and cowl without requiring removal of said bolts.

In order to fit a ventilator constructed as above to the cowl of a motor vehicle, the latter is provided with the necessary holes corwith said frames ;any suitable means such as gaskets being placed between either or both of the frames and the cowl if desired to prevent entrance of water at such points.

The ends 20 of the deflector 19 are then placed between the ends 11 of the cover and each .of the bolts or screws 24 is inserted through one of the holes 24 and its adjacent slot 25, with its head in the recess around said hole so that it lies below the outer surface of the end 11. Thedefiector plate 19 is thereupon adjusted to the desired angle to the plane of the cover 9 and the nuts on the bolts 24: are set up so as to clamp these two elements in the given relative positions. The rear edge of the cover is then inserted between the cowl and the tubular head or hearing 8 of the frame 2 and said cover is then swung toward said frame so as to cause the deflector plate 19 to pass through the opening therein and also through the openings in the cowl and in the lower frame 4. This movement of the cover is continued until the tongues or abutments 16 pass through said openings, which action is made possible by reason of the resiliency of the end elements 11 and 20 ;it being noted that with the various parts in the above positions, the pintles or tongues 22 of the deflector plate extend between the body of the cover 9 and the edges 17 of the ends 11.

For operating the cover and its associated parts, I preferably connect to the outer edge of the deflector plate 19 a rod 30 which is extended therefrom through the dash board 31 and terminates in a knob or handle 32. This rod is preferably threaded at one end for a considerable length and is screwed into a hooked terminal piece 33 which engages a flange 34 at the lower edge of the deflector be desired to apply it, since in any given case said rod is cut to the required length after the ventilator is properly app-lied and is thereafter screwed into the hooked member 33.

When use of the ventilator is not required the cover 9 may be adjusted by hand or by 7 means of the operating rod 30 until it complete-ly covers the frame 2 and rests with the edges of its flanges in engagement with the top surface of the cowl Or other structure to which it may be applied. When in such a position it alone of all the parts of the ventilator is visible and, owing to its downwardlyrfianged edges as well as to the upwardly flanged edges of the frame 2, the entrance of water through the opening in; the cowl is practically impossible. By swinging the cover into any of its several possible positions, the volume of air directed by the resiliency of into the cowl may be varied at will and said cover is retained in any of such positions the ends 11, retaining them in holding engagement with the teeth 15.

One of the important advantages of the above construction resides in its adaptability to cowls or other structures of widely differing forms, for even though there be considerable curvature to the particular surface in which the ventilator is to be mounted, the clamping action of the two frames will straighten or render plane sufficient of the edges of the opening formed for the ventilator to permit the upper frame to make a tight joint. This w1th the adjustable deflector plate in addition, makes it possible to suit the deflector to different makes of vehicles, etc., where the size of the cowl and the dimensions'and form of the space under the same is' widely varied.

By means of such adjustment the incoming current of air may be caused to flow in the desired direction practically independent of the wide variation in the various styles of vehicles. It is further to-be noted that by reason of the construction and arrangement of parts none of the latter will rattle or cause noise even though subjected to long continued vibration.

I claim:

1. The combination in a ventilator of an open frame having one edge cylindrically curved to provide a bearing; a cover having a flanged edge curved to slidably coact with said bearing edge of the frame; and segmental end members connected to the cover and movable through the frame.

The combination in a ventilator of an open frame having an edge rolled into substantially cylindrical form to provide a bearing; a cover having a portion formed to pivotally coact with said bearing edge of the frame; and end members connected to the cover and movable through the opening of the frame having portions adjacent the .axis of rotation of the cover and coacting with an edge of said opening to maintain the cover and the bearing edge of the frame in operative relation.

5. The combination in a ventilator of an open frame having a portion formed to provide a bearing; a cover pivotally cooperating with said bearing portion of the frame; end members projecting from the cover and operative in the opening of the frame, each of said members being cut away adjacent the bearing portion of the frame and cooperating with an edge of the opening of the frame to maintain the cover in operative relation with said bearing portion; and a deflector plate having pivot extensions projecting into the spaces formed between the inner edges of said end members and the cover.

6. The combination in a ventilator of an open frame having a portion of one side folded upon itself and having one of its edges curved to form a bearing structure; a cover having a flange formed to rotatably coact with said bearing structure; and end members connected to the cover in position to coact with said turned over portion of the frame to maintain the flange of the cover in operative relation with the bearin The combination in a ventilator of an open frame having an upwardly projecting marginal flange; a cover hinged to said frame and having a downwardly extending flange adapted to completely enclose said frame when said cover is in its closed position; and segmental end members attached to the cover and cooperative with an edge of the opening in said frame and the flange of the frame to pivotally connect said cover to the latter.

In witness whereof I affix my signature.
